|6. Application Of FRP. FULL|
Civil engineering structures could be damaged by several causes such as earthquakes, cyclones, blast and so on. These kinds of loading either collapse the structure prematurely or cause extensive damages to it. When the damage occurs to a limited extent, it is possible to retrofit the structure. A review of the available literature has disclosed that umpteen numbers of retrofitting methodologies are available...

|V/STOL Tandem Fan transition section model test - Simpkin, W. E|
An approximately 0.25 scale model of the transition section of a tandem fan variable cycle engine nacelle was tested in the NASA Lewis Research Center 10-by-10 foot wind tunnel. Two 12-inch, tip-turbine driven fans were used to simulate a tandem fan engine. Three testing modes simulated a V/STOL tandem fan airplane. Parallel mode has two separate propulsion streams for maximum low speed performance...

|Performance of Oil Pumping Rings: An Analytical and Experimental Study - Eusepi, M. W.|
A steady-state design computer program was developed to predict the performance of pumping rings as functions of geometry, applied loading, speed, ring modulus, and fluid viscosity. Additional analyses were developed to predict transient behavior of the ring and the effects of temperature rises occurring in the hydrodynamic film between the ring and shaft. The analysis was initially compared with previous experimental data and then used to design additional rings for further testing...

|Surface cracks in a plate of finite width under tension or bending - Erdogan, F.|
The problem of a finite plate containing collinear surface cracks is considered and solved by using the line spring model with plane elasticity and Reissner's plate theory. The main focus is on the effect of interaction between two cracks or between cracks and stress-free plate boundaries on the stress intensity factors in an effort to provide extensive numerical results which may be useful in applications...

|Reusable rocket engine turbopump condition monitoring - Hampson, M. E.|
Significant improvements in engine readiness with attendant reductions in maintenance costs and turnaround times can be achieved with an engine condition monitoring system (CMS). The CMS provides real time health status of critical engine components, without disassembly, through component monitoring with advanced sensor technologies. Three technologies were selected to monitor the rotor bearings and turbine blades: the isotope wear detector and fiber optic deflectometer (bearings), and the fiber...

|Comparison of Experimental Data and Computations Fluid Dynamics Analysis for a Three Dimensional Linear Plug Nozzle - Ruf, J. H.|
A three dimensional linear plug nozzle of area ratio 12.79 was designed by EADS Space Transportation (former Astrium Space Infrastructure). The nozzle was tested within the German National Technology Program 'LION' in a cold air wind tunnel by TU Dresden. The experimental hardware and test conditions are described. Experimental data was obtained for the nozzle without plug side wall fences at a nozzle pressure ratio of 116 and then with plug side wall fences at NPR 110...

|Full-scale flammability test data for validation of aircraft fire mathematical models - Kuminecz, J. F.|
Twenty-five large scale aircraft flammability tests were conducted in a Boeing 737 fuselage at the NASA Johnson Space Center (JSC). The objective of this test program was to provide a data base on the propagation of large scale aircraft fires to support the validation of aircraft fire mathematical models. Variables in the test program included cabin volume, amount of fuel, fuel pan area, fire location, airflow rate, and cabin materials...

|How would you define sustainability?|
In his definition of sustainability, Peter Murray talks about sustainable urban planning in London. Green architecture and retrofitting will improve energy efficiency in our homes. Transport is a major issue for sustainability; we need more urban cycling and development around transport hubs.

|Sulfur transformations at the hydrogen sulfide/oxygen interface in stratified waters and in cyanobacterial mats - Cohen, Y|
Stratified water bodies allow the development of several microbial plates along the water column. The microbial plates develop in relation to nutrient availability, light penetration, and the distribution of oxygen and sulfide. Sulfide is initially produced in the sediment by sulfate-reducing bacteria. It diffuses along the water column creating a zone of hydrogen sulfide/oxygen interface. In the chemocline of Solar Lake oxygen and sulfide coexist in a 0 to 10 cm layer that moves up and down dur...

|Can cities ever be sustainable?|
Herbert Girardet gives examples of sustainable cities. Sustainable urban planning means Copenhagen has been designed for urban cycling and walking. Copenhagen also produces electricity from renewable energy sources. Vienna is another green city and has retrofitted council houses to reduce energy use by 60-70%.
